Not a cut and dry answer. 

But if you have the time to do everything yourself, it can be a lot more lucrative (albeit more work) because you aren't giving the turnkey provider a cut of the margin to do everything for you.

It's not a cute / attractive house at all, so as a duplex it looks even worse.If it were mine, I'd turn it back to a single family.I'd upgrade the exterior. 

Preferred returns divide available profit among investors before the sponsor receives a cut, and they tend to be between 5-8%.

If you keep the tenant's security deposit (not sure you are able to without a penalty written into your lease), THEY don't get a cut of that.  

These are real estate funds put together by real estate private equity firms that acquire larger assets and fund those acquisitions by raising capital from their investor clients.There are variations on this theme--for example "crowdfunding" is where these private offerings become somewhat public by advertising their offerings on a website where investors can point and click to make an investment, and the website gets fees or a cut of the deal for being a facilitator.But the majority of money that moves in this space is done privately from the firm's existing clients and new clients that come by word of mouth and referrals. 

Or you can invest in crowdfunding deals and they take fees and a cut. 

There's even an Apple store.As mentioned before, North Scottsdale is also where big events happen like Barret Jackson, Phx Open, Arabian Horse Show, and so forth.Also, while I wouldn't suggest living there, there is a CUTE little town that you can explore not too far away from North Scottsdale. 

I see you're in Valley Village - if that's where your buildings are, I'd proceed with caution; Los Angeles is poised to implement some unfavorable regulations in the coming years, and beware of trying to STR with rent-controlled units.What you may look into is: AirBNB has what they call a "Friendly Buildings Program" where they've partnered with certain long-term landlords to allow their tenants to AirBNB their apartments in an above-board manner, and the landlord gets a cut.  

They will take a cut, but you might be able to get a better deal than paying retail off MLS.
